This invention relates to incinerators 'an'd one of the principal objects thereof is to" provide.

means for facilitating and expediting :thedisposal of excrements or other matter in latrines or the like and thereby do away with the unsanitary cesspool's, particularly in places which lack sewers. I

Another object of this invention is tol provide, a

latrine with an incinerator which will be aut matically controlled from the seat.

A still other object is to provide meansiivhich will disseminate and comminute the matter: dur ing the process of incineration.

And still other object is to provide an ash collecting means below the incinerator which can be conveniently and readily removed and emptied.

With these and other objects in view my invention consists in the novel combination, con- -struction and arrangement of' parts as will be hereinafter more fully described and defined in the appended claims.

While the present embodiment discloses the construction of an incinerator as applied to a latrine such as used in outhouses, I do not wish to confine myself to the details of construction described and shown herein since the structure may be modified in various cases to make theincinerator applicable for latrines in, railroad trains, trailers, airplanes, etc., without departing from the principle of my invention.

Moreover under the term electric incinerator I wish to include heating elements as used in connection with toasters, irons, etc., as well as high and low frequency electric circuits as used with electric furnaces.

In the accompanying drawing which constitutes part of this specification and ,in which similar reference characters denote corresponding parts:

Figure l is a vertical section of a latrine equipped with an electric incinerating device constructed in accordance with my invention,

Figure 2 is a cross section on line 2-2 of Figure l, and

Figure 3 is a diagram of the electric circuits controlled from the seat of the latrine.

In the present example the latrine is shown to comprise an open bottomed bowl l0 mounted over an incinerating chamber ll formed of suitable material. The walls of the bowl slope out wardly in downward direction and at their lower edges are flush with the upper edges of the incinerating chamber.

I The incinerating means, according to this example, comprises heating elements in form of high resistant coils l2 such as ordinarily used in electric toaster, electric irons, etc., and of which several (in the present example two) are arranged in a horizontal plane below the bottom of the bowl or near the upper end of the incinerating chamber. These coils extend longitudinally through hollow rollers of heat conducting material [3 whose journals 13a, 131), are suitably and frotatively supported in the opposite walls of the incinerating chamber ll. ranged in as close proximity to one another as possible so as to obstruct direct passage from These rollers are arthe bowl into the ash collecting chamber 22 and serve at the same time as mangles whereby the matter dropping onto the rollers when the latter are rotated will be comminuted and its burning to ashes expedited. The rollers may be provided with radial ribs M of metal or other heat conducting material distributed. closely next to one another around the entire circumferential faces thereof. The ribs of one roller are displaced relative to those of the adjacent roller so as to mesh with one another and fonn a sort of grate, which will receive the matter dropping down the bowl and when the rollers are rotatedassist in disseminating and comminuting the same and thereby more effectively cause the burning thereof.

The rollers may also be arranged in two or more vertical tiers, in which those of one tier are displaced horizontally to the adjacent tier.

I5 denotes an electric motor from which through suitable transmission l6 rotation is imparted to the set of rollers l3. The electric circuit for said motor is controlled by means of a suitable time switch I"! which is automatically operated from the seat of the bowl. To this end the switch [1 comprises two circular concentric contact shoes Ila, vl'lb insulated from one another and a contact arm He. The contact arm He is mounted on an output shaft of a speed reducing gear 18 driven from an electric motor l9. The contact shoes Ila, [7b are incomplete circles, the edges thereof at one end being in radial alinement, while the edges at the opposite end are out of alinement, so that the gap between the ends of one shoe segment is wider than. that of the other. The electric circuit operating motor l9 and the heating coils I2 is controlled through contact of the contact arm Ho and segment Ila While the electric circuit operating the motor I5, is controlled through contact arm He in cooperation with contact segment 11b.

The contact arm He is radially extended beyond the contact shoes and is adapted to be operated from a finger 20 projecting from the lid 2| hingedly mounted on the' seat of the bowl In. The finger 20 has'a resilient or yielding member 20a which when the lid is moved into closing position will engage the outer end of the contact arm I10, and move the latter from its position in the gaps onto the contact segment Ha, thereby first closing the electric circuit through the motor l9, setting the arm l'lc into rotation, and at the same time through the heating elements I2. When the arm llc reaches the other contact shoe llb, which is after the resistance coils have been heated to the desired temperature, the electric circuit through the motor 15 is closed as a result of which the heated rollers l3 commence to turn delivering the ashes to the ash collecting chamber 22. The incineration process continues as long as the contact arm is in contact with the contact shoes Ha, I 1b. When it slides off the same and enters the gaps the circuit is broken.

When the lid 2| is opened for use the member 20a of the finger 20 can pass the contact arm llc without moving the latter from its inactive position within the gaps. Suitable packing means maybe provided between the lid and the seat to produce a tight closure when the lid is closed.

23 denotes a fume and odor escape passage which may lead from the upper part of the incinerator a sufiiciently long distance away from the latrine. Within th ash collecting chamber 22 a wheeled receptacle 24 may be provided which by means of a cable 24a may be hauled outwardly through a passage 22a over an inclined bottom 221) or rails.

The mode of operation is as follows:

As long as the lid is in open position the incinerator is out of operation. When .the lid is moved into closing position its finger 20 will turn the arm l'lc from the lower ends of the con- I energizing the motor operating the rollers, as a result of which the heated rollers will be rotated causing the dissemination and comminution of the burning matter and passing the ashes into the collecting receptacle.
